Sealing materials

Choosing materials is a task that often requires a lot of investigation and compromises between different desirable properties. At Seal Engineering AS we have great experience of choosing the right material for a given application, and therefore we are well prepared to help you choose the right material.

HPU™ is a hydrolysis-resistant thermoplastic polyurethane elastomer. HPU's high resistance to hydrolysis (hydrolysis is degradation in water) is rarely found in polyurethanes. It is stable in water up to 90°C and has an outstanding stability in mineral oil.
